So here's my issue. I take quite a few pictures of my screen with my phone (Nexus 5). And I'm on an iMac. So here's what it looks like when I take a picture of my screen.
As you can see there's a rainbow looking effect on the left side. And overall the picture looks distorted. Here's my question. Is there a reason why this is happening? And how can I prevent it? I'm sorry if this has been answered else where, I just don't know what to search for. Thanks in advance.
